-let air dry
-carefully replace MAF, beign sure to get it pointed the correct direction (plug in front, not in back)
-reset ECU to clear out the AF Learned trims

and im really surprised that 'most' people that have polled do not clean their MAF. I guess as a Ford tech, and seeing how many engines have been DESTROYED by faulty MAF sensors...I am over cautious.

BTW, by DESTROYED, it has ALWAYS been from an engine running lean. 'usually' from dirty air filters (lack of maintenance by the customer) and/or oil bath filters.
